TYPE
NAME
FUNCTION
A1
1
POWER
VUART
UART Supply Voltage. VUART powers the internal UART transmitter and receiver.
Connect a regulated voltage between +2.7V and +3.3V to VUART. Bypass VUART to
GND with a 0.1F ceramic capacitor.
A2
2
OUTPUT
RX
UART Receive Output. In UART mode, RX is a level-shifted output that expresses
the logic state of D+.
A3
3
INPUT
TX
UART Transmit Input. In UART mode, D- follows the logic state on TX.
A4
4
OUTPUT
BD
USB Detect Output. When VBUS exceeds the VTH-BUS threshold, BD is logic-high
to indicate that the MAX3349E is connected to a USB host. The MAX3349E
operates in USB mode when BD is logic-high, and operates in UART mode when
BD is logic-low.
B1
15
POWER
VL
Digital Logic Supply. Connect a +1.4V to +2.75V supply to VL. Bypass VL to GND
with a 0.1F or larger ceramic capacitor.
B2
16
I/O
VM
Receiver Output/Driver Input. VM functions as a receiver output when
OE = VL. VM
follows the logic state of D- when receiving. VM functions as a driver input when
OE = GND (Tables 2 and 3).
B3
5
I/O
VP
Receiver Output/Driver Input. VP functions as a receiver output when
OE = VL. VP
follows the logic state of D+ when receiving. VP functions as a driver input when
OE = GND (Tables 2 and 3).
B4
6
OUTPUT
RCV
Differential Receiver Output. In USB mode, RCV is the output of the USB
differential receiver (Table 3).
C1
14
POWER
VTRM
Internal Regulator Output. VTRM provides a regulated +3.3V output. Bypass VTRM
to GND with a 1F ceramic capacitor. VTRM draws power from VBUS. Do not power
external circuitry from VTRM.
C2
13
INPUT
ENUM
Enumerate Input. Drive ENUM to VL to connect the internal 1.5k
resistor from D+
to VTRM (when VBUS is present). Drive ENUM to GND to disconnect the internal
1.5k
pullup resistor. ENUM has no effect when the device is in UART mode.
C3
8
INPUT
SUS
Suspend Input. Drive SUS low for normal operation. Drive SUS high to force the
MAX3349E into suspend mode.
C4
7
INPUT
OE
Output Enable. Drive
OE low to set VP/VM to transmitter inputs in USB mode. Drive
OE high to set VP/VM to receiver outputs in USB mode. OE has no effect when the
device is in UART mode.
D1
12
POWER
VBUS
USB Supply Voltage. VBUS provides power to the internal linear regulator when in
USB mode. Bypass VBUS to GND with a 0.1F ceramic capacitor.
D2
11
I/O
D+
USB Differential Data Input/Output. Connect D+ directly to the USB connector.
D3
10
I/O
D-
USB Differential Data Input/Output. Connect D- directly to the USB connector.
D4
9
POWER
GND
Ground

EP
—
EP
Exposed Pad. Connect exposed paddle to GND.
